I want to dynamically read the height and width while winform is sizable. That is, after running the form the value of these can be changed with the change of form size. If I use

C#

this.height or this.width

it can read only initial value.

Not true. And remember that C# is case-sensitive.

It's simple :)

C#

private void Form1_Resize(object sender, EventArgs e)
{
    label1.Text = this.Width + "," + this.Height;
}

No, the Height and Width properties reflect the current size of the form.
To prove it, add a label, and the following code to your Load event handler:

C#

private void Form1_Load(object sender, EventArgs e)
    {
    Timer t = new Timer();
    t.Interval = 100;
    t.Tick += new EventHandler(t_Tick);
    t.Start();
    }

Then add the handler:

C#

void t_Tick(object sender, EventArgs e)
    {
    label1.Text = string.Format("{0}:{1}", Width, Height);
    }

Run your app, and look at the label while you resize the form.
